ABC News has learned exclusively that Alice Stewart has been hired by the Rick Santorum campaign as its national press secretary.

Stewart previously served as spokeswoman Michele Bachmann's presidential campaign and played the same role for Mike Huckabee's 2008 bid.

She also worked for Huckabee's Political Action Campaign, HuckPAC, with Santorum's current national communications director Hogan Gidley. Gidley hired Stewart for the Santorum campaign.

On Friday the Santorum campaign announced it had raised $3 million since the former Pennsylvania senator's trifecta win in Colorado, Minnesota and Missouri on Tuesday.

That's $1 million a day since his victory speech in Missouri. The campaign said it would use the funds to add staff, and Stewart is the first high profile hire since those wins.

"I am very honored and proud to join Team Santorum," Stewart said in a statement. "Senator Santorum has proven himself to be the true, consistent conservative in this race. Rick's growing momentum is evidence that voters realize he's the only candidate with the conservative record we need to stop Mitt Romney and beat President Obama."
